That is limited thinking. People are replacing their bosses, and your boss will be bossing what exactly? Right now LLMs cant' replace the entire spectrum of human intelligence. But if your entire work is just translating your boss ask to for-loops & if-statements, the I guess yes, I would be worried.
And what is your point? again, the tool is here to stay, it won't replace software engineers as of now, you can't undo progress, so what is your point exactly?
Same point as the textiles industry in the 18th century..and software engineers automating other industries for the last 50 years for what? for fun?
My point is that you implied this question had a simple answer but you are failing or refusing answer it. I have just disproven, by the Socratic method, your statement that "people are replacing their bosses".
